A Wallabies official confirmed on Monday that while she is not talking yet, Trish Douglas's condition continues to improve after suffering a stroke late on a flight to London where she was heading to watch her son play.

She was placed in an induced coma.

Douglas caught an early train to London on Sunday to be with his mother while his two brothers Luke and Jake have both flown to the UK.

The Wallabies play England in the second match of their European tour at Twickenham on Saturday (Sunday (AEDT).
